To all whom it may concern:

Be it known that I, I{ARLIBERGSKAUG, a citizen of the United States, and resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a. new and Improved Packing-Tool, of which the following is a full clear, and exact description.

My invention relates to a packing tool and aims to provide a device of this character more particularly adapted for use in connection with the packing of tubes.

With regards to condenser tubes, it is a well appreciated fact that considerable difli-.

culty has been experienced in applying the packing associated with the heads of the tubes and the ends applied thereto, in that it has been necessary to utilize great care in applying the packing material.

For this purpose a tool has also been employed, which has been, to say the least highly inefficient in that constant care is necessary to properly complete the operation.

From the foregoing it will be seen that in connection with this class of work, it is necessary to employ a mechanic skilled in the application of packing, thus increasing the expense of this operation, aside from the fact that a skilled worker is incapable of packing more than an extremely limited amolpnt of tubes within the course of a days wor Aside from this, it is also well known by those conversant with the operation referred to, that even with the best of care, tubes must be frequently readjusted, and that also even a skilled mechanic will very often improperly perform the operation, necessitating this being again resorted to, thus delayin the work and adding to the expense.

.in the direction of vision of a tool of the character stated b means of which the tube will be evenly and correctly packed, so that it will not be necessary to resort to duplicate work to insure proper packmg.

other object of my invention is the construction of a tool in which a far greater amount of packmgs may be accomplished than has heretofore been possible, thus reduc ng the expense of this operation to a mmnnum.

Further objects of my invention will appear in the annexed specification and drawlngs which latter present one practical embod ment of my invention, and in which-- Flgure 1 1s a plan of a tool embodying my imlproved construction.

. Fig. 5 is a sectional view taken through the body of the tool along the line 55 and the arrows indicated in along of the arrows 1g. 6 is a partly sectional view of the pos tlon WhlOh the parts assume upon their init al application to a tube and head.

Fig. 7 1s a viewsimilar to'Fig. 6 but showmg the second stage of the operation.

1g. 8 illustrates the third stage of the operation accomplished.

F 1g. 9 shows the essential elements in the posltion they assume when the packing operation has been practically completed, and

Figs. 10 and 11 are perspective views of the main elements of the tool.

In these views the reference numeral 15 indicates the tube to be packed, to which the head 16 is applied, including a body portion presenting screw threads 17, and having, in the usual. manner, an annular recessed part 18 extending below and forming a continuation of the screw threaded portion 17 it be- Patented Oct. 11, 1921.

my improved. packing tool, it will not be necessary to employ an expensive form of packing, strip material 19 being utilized for this purpose.

Also, reference being had to Fig. 1, it will be seen that the tool includes in its essential elements, a stem 20, handle 21, and a sleeve 22, surrounding the lower end of the handle.

With regard to the detailed construction, it will be noted, reference being had to Fig. 3, that the handle 21 is of a diameter sufli: cient to permit of its inner end being introduced into the sleeve 22 and it is to be noted that shoulders 23, forming a part of both the handle and sleeve serve to force these two elements in opposite directions by means of a spring 24 interposed therebetween.

It will also be seen thatthe stem 20 is preferably formed with a shoulder 25 normally. lying in a plane beyond the outer edge of the sleeve 22, it being noted that the body of the stem 20, comprising an enlarged portion 26 is slidably mounted within the handle 21 and presents annular grooves 27 adjacent the outer end of the sleeve 22 for a purpose hereinafter more fully specified.

It will also be noted that a screw or other suitable element 28 cooperates with the longitudinally extending slot 29 forming a part of the sleeve 22, this element engaging the inner end of the handle 21 and extending beyond the same to within one of the grooves 27 Thus all of the parts are permitted to move with respect to each other within certain limits, and it is to be noted that the stem 20, sleeve 22 and the handle 21 may be secured in fixed relationship one with re spect to each other bymeans of a movable latch 30 pivotally secured as at 31 to the sleeve 22, and being capable of extending to an opening 32 formed in the handle 21 to project into the secondary groove 27 In operation it will be noted that, as has been indicated in Fig. 6, a strip of packing material 19]" is brought to a position at which one of its ends will rest within the notch 33 forming a part of the sleeve 22 the body of said packing material passing around the stem 15 and through the notch 34. The oper ator now inserts the stem 20 into the tube 15 and upon exerting an inward control,

subsequent to the release of the latch 30 which is now swun as in Fig. 6, to act as a guiding element %or the material 19, the shoulder 25 of the stem 20 will contact with the outer edge of the tube 15 and result in a'movement of this element with respect to both the stem and sleeve 22 against the action of the spring 24 and this latter movement will result in a projection of the acking material 19 from the position indicated in Fig. 6, to that illustrated in Fig. 7 i. e. into the recess 18.

Inthis connection it is to be noted, as

has been illustrated. in Fig. 6, that the outer edge of the sleeve 22 will contact with the head16, and this together with the seating established between the tube 15 and shoulder 25 of the stem 20 will insure a firm cooperation of the parts one with the other.

A maintenance of the pressure exerted upon the handle 21 and a simultaneous rotation of the same will cause the packing material .to be disposed in the manner illustrated in Fig.. 8, and it will be noted that any damage to this material incident to the sharp edges of the various obviated, reference being ha to Figs. 9 and 11, by means of the curved lateral edge 35 of'the slot 36, forming part of the handle 21, which slot accommodates a portion of the packing material 19 when the parts are in the positions illustrated in Figs. 7 8 and 9.

From the foregoing it will be appreciated that I have constructed a packing tool, particularly intended for use in connection with condenser tubes, but as aforestated not necessarily limited to this class of work, which tool will be extremely simple in construction, and by means ofi which an unskilled operator will be capable of efi'ecting a packing of a greater number of tubes, aside from the fact that each packing operation will be. perfectin all details, it being noted that, as has been illustrated in Fig. 8, the end of the-p'ackingmaterial 19 will be fed through into the recesses 18 so that even a severance of the material, subsequent to its application to. the tool is avoided.

It will further be appreciated that numerous modifications of structure might readily be resorted to without in the least departing from the spirit of my invention, which I claim as- 1. A packing tool, including a stem, sleeve and handle, and means carried by said sleeve and adapted to co-act with'said handle for normally forcing said sleeve "and handle in opposite directions with respect to .each other.

2. A packing tool, including a stem, handle and sleeve, said sleeve partially inclosing said handle and stem, shoulders forming a part of said sleeve and handle, and a spring introduced between said shoulders.

3.

5. A packing tool,

including stem, sleeve and handle movable with respect to each other, and a latch movably secured to said sleeve and being adapted when the parts are in locked position with respect to each other, to extend into a groove forming a part of said stem through a slot in said handle.

6. A packing tool, including a sleeve, handle and stem, said sleeve presenting notches in its outer edge, said handle being formed with a slot in its outer end and adjacent said notches.

7. A packing tool including a sleeve, handle and stem movable with respect to each other, said sleeve being formed with a reduced ortion in its inner face, said handle being ormed with a shoulder, a spring arranged within the reduced portion of said sleeve, and having one of its ends bearing against the shoulder of said handle, its opposite end bearing against the inner end of the reduced portlon whereby to normally tend to force said handle in a direction opposite tothe tendency imparted to said sleeve, and means for limiting said movement.

8. A packing tool including a handle, sleeve and stem, said handle being formed with a slot in its outer end and being partially arranged within said sleeve, said stem being disposed within said handle and extending beyond the same, one of theside edges of said slot being curved adjacent its outer end.
